Description

Technical Field

[0001] This utility model relates to the technical field of waste gas purification equipment, and in particular to a waste gas purification equipment for a coke oven heating exchanger. Background Technology

[0002] During the coke oven production process, the exhaust gas generated by the coke oven heating exchanger contains a large amount of harmful substances, such as dust and harmful gases. If this exhaust gas is discharged directly without effective treatment, it will not only cause serious environmental pollution, but also endanger the health of nearby residents.

[0003] Currently, existing coke oven heating exchanger exhaust gas purification equipment on the market has certain shortcomings in terms of purification effect and operational stability. For example, some purification equipment has uneven spraying effect, resulting in insufficient contact between exhaust gas and purification liquid, which affects purification efficiency. In addition, the exhaust gas flow in the spray tower is relatively fast, which can easily lead to insufficient contact between exhaust gas and purification liquid, affecting purification quality. Therefore, we propose a coke oven heating exchanger exhaust gas purification equipment to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a coke oven heating exchanger exhaust gas purification device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A coke oven heating exchanger exhaust gas purification device includes a purification spray tower for the exhaust gas from the coke oven heating exchanger. An exhaust gas connection pipe connected to the exchanger is installed on one side of the purification spray tower, and an exhaust pipe is installed on the top of the purification spray tower. A partition is installed inside the purification spray tower, and a rotating shaft is rotatably installed at the bottom of the partition. A crossbar is fixedly installed at the bottom of the rotating shaft, and an annular spray pipe is installed on the crossbar. Multiple grooves are evenly spaced on the top of the partition, and exhaust holes are formed on the inner wall of the bottom of the grooves.

[0007] Preferably, a liquid supply pipe for supplying liquid to the annular spray pipe is installed on the other side of the purification spray tower, and a flexible hose is installed between the liquid supply pipe and the annular spray pipe.

[0009] Preferably, a rotating shaft is rotatably mounted on the inner walls of both sides of the groove, and a sealing plate is fixedly mounted on the rotating shaft, and the sealing plate is adapted to the corresponding air outlet.

[0010] Preferably, a counterweight is mounted on the top of the sealing plate via a detachable mechanism.

[0011] Preferably, a protective shell is fixedly installed on the top of the partition, a movable groove is provided on the inner wall of the top of the partition, a movable plate is slidably installed in the movable groove, a rectangular seat is fixedly installed on one side of the movable plate, and a transmission mechanism is provided between the rectangular seat and the rotating shaft.

[0012] Preferably, the transmission mechanism includes a rack and a rotating gear. The rack is fixedly mounted on the front side of the rectangular base, and the rotating gear is fixedly mounted on the top of the rotating shaft, with the rack meshing with the rotating gear.

[0013] Preferably, a drive motor is installed on one inner wall of the protective shell, a reciprocating screw is fixedly installed on the output shaft of the drive motor, and the moving plate is threaded onto the reciprocating screw.

Detailed Implementation

[0022] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0023] This application discloses a coke oven heating exchanger exhaust gas purification device.

[0024] Reference Figure 1-4 The coke oven heating exchanger exhaust gas purification equipment includes a purification spray tower 101 for the exhaust gas of the coke oven heating exchanger. An exhaust gas connection pipe 102 connected to the exchanger is installed on one side of the purification spray tower 101, and an exhaust pipe 103 is installed on the top of the purification spray tower 101. A partition 201 is installed inside the purification spray tower 101. A rotating shaft 202 is rotatably installed at the bottom of the partition 201. A crossbar 203 is fixedly installed at the bottom of the rotating shaft 202. An annular spray pipe 204 is installed on the crossbar 203. Multiple grooves 301 are equally spaced on the top of the partition 201, and exhaust holes 302 are opened on the bottom inner wall of the grooves 301.

[0025] In this embodiment, a liquid supply pipe 205 for supplying liquid to the annular spray pipe 204 is installed on the other side of the purification spray tower 101. A flexible hose 206 is installed between the liquid supply pipe 205 and the annular spray pipe to facilitate liquid supply when the annular spray pipe 204 rotates, ensuring a continuous and stable delivery of purified liquid during the rotation of the spray pipe and avoiding the impact of liquid supply interruption on the purification effect.

[0026] In this embodiment, a drain pipe 207 for waste liquid discharge is installed on one inner wall of the purification spray tower 101, and a valve body is installed on the drain pipe 207 to facilitate the control of waste liquid discharge. The waste liquid can be discharged into the recycling equipment in a timely manner according to the accumulation of waste liquid during the purification process, so as to prevent excessive waste liquid from affecting the purification effect and reduce the risk of internal corrosion of the equipment.

[0027] In this embodiment, a rotating shaft 303 is rotatably installed on the inner walls of both sides of the groove 301. A sealing plate 304 is fixedly installed on the rotating shaft 303, and the sealing plate 304 is adapted to the corresponding air outlet 302. This can prevent the exhaust gas from being discharged without sufficient purification. The precise adaptation of the sealing plate 304 ensures that the exhaust gas can only be discharged under certain purification and pressure conditions, thereby improving the purification quality. A counterweight 305 is installed on the top of the sealing plate 304 through a detachable mechanism. The opening pressure of the sealing plate 304 can be adjusted according to actual needs to achieve flexible control of exhaust gas emissions under different working conditions and adapt to various coke oven production scales and exhaust gas treatment requirements.

[0028] In this embodiment, a protective shell 401 is fixedly installed on the top of the partition 201. A movable groove 402 is provided on the inner wall of the top of the partition 201. A movable plate 403 is slidably installed in the movable groove 402. A rectangular seat 404 is fixedly installed on one side of the movable plate 403. A transmission mechanism is provided between the rectangular seat 404 and the rotating shaft 202. The transmission mechanism includes a rack 405 and a rotating gear 406. The rack 405 is fixedly installed on the front side of the rectangular seat 404, and the rotating gear 406 is fixedly installed on the top of the rotating shaft 202. The rack 405 and the rotating gear 406 mesh with each other. The rotation of the rotating shaft 202 is realized through the transmission mechanism. This meshing transmission method has the characteristics of high transmission efficiency and high motion accuracy. It can accurately transmit the power of the driving device to the spraying system and ensure the uniformity of the spraying effect.

[0029] In this embodiment, a drive motor 501 is installed on one inner wall of the protective shell 401. A reciprocating screw 502 is fixedly installed on the output shaft of the drive motor 501, and a moving plate 403 is threaded onto the reciprocating screw 502. The drive motor 501 drives the reciprocating screw 502 to rotate, thereby causing the moving plate 403 to move back and forth in the moving groove 402. This reciprocating motion design enables the annular spray pipe 204 to achieve periodic rotational spraying, expand the spray coverage area, and significantly improve the contact area and reaction efficiency between the exhaust gas and the purification liquid.

[0030] In this invention, the drive motor 501 is started, which drives the reciprocating lead screw 502 to rotate. Since the moving plate 403 is threaded onto the reciprocating lead screw 502, the moving plate 403 makes reciprocating linear motion within the moving groove 402. The moving plate 403 drives the rectangular seat 404 to move. The rack 405 on the rectangular seat 404 meshes with the rotating gear 406, thereby causing the rotating shaft 202 to rotate reciprocally. The rotating shaft 202 drives the crossbar 203 and the annular spray pipe 204 to rotate reciprocally. The purified liquid enters the annular spray pipe 204 through the liquid supply pipe 205 and the hose 206, and is sprayed out from the nozzle of the annular spray pipe 204. Through the reciprocating rotation of the annular spray pipe 204, the spraying at the four corners can be reduced, thereby achieving the purpose of fully purifying the exhaust gas.

[0031] When the exhaust gas generated by the coke oven heating exchanger enters the purification spray tower 101 through the exhaust gas connection pipe 102, it comes into full contact with the purification liquid sprayed from the annular spray pipe 204 below the baffle 201 for preliminary purification. As the exhaust gas rises, when the exhaust gas pressure reaches a certain level, it pushes the sealing plate 304 in the groove 301 to rotate around the rotating shaft 303, opening the exhaust port 302. The exhaust gas continues to rise and be discharged through the exhaust port 302. Through the cooperation of the sealing plate 304 and the exhaust port 302, the residence time of the exhaust gas in the purification spray tower 101 can be increased, so that the exhaust gas and the purification liquid can come into full contact.

[0032] Waste liquid generated during the purification process is discharged through the drain pipe 207 on one side of the inner wall of the purification spray tower 101. By opening the valve on the drain pipe 207, the waste liquid can be discharged into the designated collection device.

[0033] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
